IndustryNAICS 92216Public Administration

Fire Protection (United States) — NAICS 92216

1. Overview

NAICS 92216 is the "industry" level of the North American Industry Classification System (NAICS — the U.S. government's standard code for industries) that covers government firefighting and fire prevention. At this level it is a rollup, but a rollup of exactly one thing: it contains a single, identically defined child industry, 922160 Fire Protection. There is no aggregation happening here — 92216 is 922160.

The substance is the same as its child: municipal, county, township, and special-district fire departments — the roughly 29,000-plus departments and about a million career-plus-volunteer firefighters who respond when you call 911 for a fire, a crash, or (most often) a medical emergency [1][3]. Because the service is delivered by governments and unpaid volunteers, there is no stock that "is" the fire service. The investable question is who gets paid to equip, supply, build, service, insure, and litigate around this roughly $79-billion-a-year government function — a supply chain of fire-truck makers, sprinkler and alarm firms, life-safety inspection roll-ups, safety-gear makers, private ambulance and wildfire-aircraft operators, chemical companies carrying PFAS liabilities, and the municipal-bond market that funds the departments [6].

For the full treatment — the investable universe, how each layer earns, demand drivers, regulation, consolidation, risks, and how to invest — read the child primer, [922160 Fire Protection]. This page is a short pointer that gives 92216's own figures and explains why the two levels are the same.

2. What's inside — and why this level equals its one child

NAICS breaks the economy into nested levels: sector (2-digit) → subsector (3-digit) → industry group (4-digit) → industry (5-digit) → national industry (6-digit). Code 92216 sits at the 5-digit "industry" level, and the 2022 NAICS structure gives it exactly one 6-digit national industry beneath it:

Child code Name Share of this level
922160 Fire Protection 100%

When a 5-digit industry has a single 6-digit child, the two are definitionally identical — same scope, same establishments, same statistics. The "6-digit" code exists only to complete the hierarchy, not to subdivide anything. So everything true of 922160 is true of 92216: it captures government establishments primarily engaged in firefighting and fire prevention, including departments that combine fire protection with ambulance or rescue service [1]. It excludes the adjacent codes where nearly all the investable activity actually lives — combined police-and-fire (922120), commercial/wildfire firefighting services (561990), standalone ambulance service (621910), alarm monitoring (561621), sprinkler installation (238220), and the various equipment-manufacturing codes [1].

3. How big it is

Our federal ground-truth note. Histometrics has no ingested Census/SBA business statistics for NAICS 92216 — and, as with its child, that absence is itself the story. The standard federal business datasets (County Business Patterns, the nonemployer series, SBA small-business tallies) count private employer firms and self-employed workers, and County Business Patterns explicitly excludes most government establishments [2]. Because 92216 is a government function staffed largely by volunteers, those datasets structurally undercount it toward zero. The real size shows up in government-finance and fire-service statistics instead. Because this level equals 922160, the figures are the child's figures:

  • Government spending: state and local governments spent about $79.2 billion on fire protection in 2024 (U.S. Bureau of Economic Analysis); inflation-adjusted local fire spending roughly tripled from 1980 to 2019 [6][3].
  • Departments and people: roughly 29,000-plus fire departments and about 1.0–1.05 million firefighters, of whom about 65% are volunteers, per NFPA's U.S. Fire Department Profile (NFPA = National Fire Protection Association, the main U.S. fire-data and codes body) [3].
  • Unpriced volunteer labor: NFPA values donated volunteer time at roughly $140 billion a year — a "cost" no budget or company books record, and the main reason the sector looks small in dollars but is enormous in real terms [7].
  • Workload: U.S. departments field on the order of 35 million calls a year, only about 4% of them actual fires and roughly two-thirds medical/rescue [4].

The headline is unchanged from the child: demand is huge and growing, but this is a public cost center, not a profit pool. The profit pool is in the supply chain — detailed in [922160 Fire Protection].

4. Investable universe — where value concentrates

There is no listed pure-play that "is" the fire service. Because 92216 has only one child, value concentrates exactly where the 922160 primer maps it — in the private supply chain around the government demand engine, not in the code itself:

  • Fire apparatus (trucks): a tight oligopoly — REV Group (NYSE: REV), Oshkosh/Pierce (NYSE: OSK), and Rosenbauer (Vienna: ROS) hold an estimated 70–80% of the U.S. market [10][11][12].
  • Fire-protection systems and services (install / inspect / test / monitor): APi Group (NYSE: APG) is the closest listed proxy; Johnson Controls (NYSE: JCI) and Honeywell (Nasdaq: HON) offer larger but diluted exposure [13][14][16].
  • Safety equipment, detection, distribution: MSA Safety (NYSE: MSA), Resideo (NYSE: REZI), ADT (NYSE: ADT), Core & Main (NYSE: CNM) [17][18][19][20].
  • Aerial wildfire suppression: Bridger Aerospace (Nasdaq: BAER), small and seasonal [22].
  • The demand side itself: held via municipal, county, and special-fire-district bonds — the fixed-income route to lending into fire departments [1].
  • Private capital: private-equity-backed service platforms (Pye-Barker, Summit, Sciens, Fortis, Encore, KiddeFenwal) and the private EMS/fire contractor Global Medical Response/AMR [24][25][26][27][28][29].

Full company tables, ownership, and scale caveats are in [922160 Fire Protection §4].

5. How the money works

The government service is a cost center funded by local property taxes, special-district levies, bond issues, some EMS transport billing, and federal grants — a fire department earns no return, and for a bond investor the metrics are tax base, levy, pension load, and coverage, not profit [6]. Everyone else earns off the supply chain: apparatus makers run a long-cycle, backlog-driven capital-goods business (a modern pumper now runs about $1 million, a ladder truck about $2 million, with two-to-four-year lead times) [11]; systems-and-services firms earn a code-mandated installation plus recurring inspection/testing/monitoring annuity [13]; equipment makers sell into replacement cycles; and private fire/EMS contractors earn thin, reimbursement-exposed margins [22]. See [922160 Fire Protection §5] for the layer-by-layer economics.

6. Demand drivers

The same forces that drive 922160 drive 92216: fire and building codes plus insurance that turn systems into annuities; aging building stock; critical-facility construction (data centers, advanced manufacturing, healthcare); an aging population that has quietly made the fire service mostly an emergency-medical service; wildfire and the wildland-urban interface as the fastest-growing structural theme; the apparatus replacement cycle; and municipal budgets plus federal grants [4][9][13][11][30]. Detail in [922160 Fire Protection §6].

7. Regulation

Fire protection is unusual in that the industry is also a regulator — departments enforce fire codes. The sector is shaped by NFPA consensus codes (e.g., NFPA 13 sprinkler design, NFPA 25 inspection/testing/maintenance) that create much of the demand [29]; OSHA fire-protection and firefighter-safety rules [30]; ICC model codes enforceable only after a local authority having jurisdiction (AHJ) adopts them [28]; FEMA grants (AFG and SAFER) that move the low end of the equipment and staffing market [30]; and EPA PFAS rules (per- and polyfluoroalkyl substances, "forever chemicals") phasing PFAS out of firefighting foam and turnout gear [23]. Full detail in [922160 Fire Protection §7].

8. Consolidation

Apparatus is a consolidated oligopoly now under political scrutiny — a September 2025 Senate subcommittee hearing and a Warren/Banks bipartisan investigation pressed the three truck makers on multi-year delays and roughly doubled prices [11]. The services layer is fragmented and consolidating fast, with private-equity platforms rolling up inspection/testing/monitoring firms to build geographic density and cross-selling [13]. Private fire/EMS consolidated around Global Medical Response. See [922160 Fire Protection §8].

9. Risks

The child's risk map applies in full: PFAS/AFFF liability (aqueous film-forming foam), the big one — 3M's ~$10.3B and DuPont/Chemours/Corteva's ~$1.185B public-water settlements plus thousands of pending personal-injury suits [23]; government-budget dependence on property-tax health; the volunteer-staffing crisis [3]; apparatus cost inflation and delays [11]; fixed-price project execution risk [13]; quality/liability exposure on failed systems; wildfire catastrophe risk that cuts both ways [9]; roll-up/leverage risk; and EMS reimbursement pressure. Detail in [922160 Fire Protection §9].

10. How to invest & outlook

Because 92216 equals 922160, the playbook is identical. Public-market routes: systems-and-services annuities (APG, plus diluted JCI/HON); the concentrated, cyclical apparatus bet (OSK, REV, ROS); safety/detection/distribution suppliers (MSA, REZI, ADT, CNM); the small wildfire play (BAER); and municipal bonds as the fixed-income way to lend into the demand side. Treat Carrier (NYSE: CARR) as a negative comparator after its 2024 Fire & Security exit, and the chemical names (3M, DuPont/Chemours/Corteva) as a PFAS liability story, not a growth play [13][14][16][10][11][12][17][18][19][20][21][22][23]. A discipline for all the public names: segment revenue is not fire-protection revenue unless disclosed separately. Private routes: PE-backed service platforms, private equipment makers, private EMS/fire contractors, and direct purchase of municipal and fire-district debt.

Outlook (forward-looking judgment, not established fact): durable but moderate growth — an apparatus replacement supercycle working down backlogs, steady code-driven service revenue, rising wildfire spending, aging-population EMS demand as the most durable driver, and a PFAS transition that is both a liability drag and a replacement tailwind. Swing factors are federal grant funding, municipal fiscal health, and the antitrust/procurement outcome of the fire-truck pricing investigation. For the complete analysis, see [922160 Fire Protection §10].
